      <ContactNo>1234567890</ContactNo>

以下示例演示了appendChild 屬性的用法:

<!DOCTYPE html>
<html>
   <head>
      <script>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.open("GET",filename,false);
            xhttp.send();
            return xhttp.responseXML;
         }
      </script>
   </head>
   <body>
      <script>
         xmlDoc = loadXMLDoc("/dom/node.xml");

         create_e = xmlDoc.createElement("PhoneNo");

         x = xmlDoc.getElementsByTagName("FirstName")[0];
         x.appendChild(create_e);
         document.write("Appended child is : ")
         document.write(x.getElementsByTagName("PhoneNo")[0].nodeName);
      </script>
   </body>
</html>

執行

將此檔案儲存為伺服器路徑上的nodemethod_appendchild.htm(此檔案和node.xml應位於伺服器上的同一路徑)。我們將得到如下所示的輸出:

Appended child is : PhoneNo
dom_node_object.htm
